NImzo-Indian defence

Today,I would like to share with you a lecture I prepared a New opening on Nimzo-Indian defence,some times Called as Nimzovitch defence.This hypermodern opening was developed by GrandmasterAron Nimzowitsch who introduced it to master-level chess in the early 20th century. Unlike most Indian openings the Nimzo-Indian does not involve an immediate fianchetto, although Black often follows up with ...b6 and ...Bb7. By pinning White's knight Black prevents the threatened 4.e4 and seeks to inflict doubled pawns on White. White will attempt to create a pawn centre and develop his pieces to prepare for an assault on the Black position.
